Psalm for Band, by Vincent Persichetti, was commissioned by the
Alpha Chapter of Pi Kappa Omicron National Band Fraternity at the University
of Louisville.
It was first performed in 1952 by the University of Louisville Concert Band
with the composer conducting.
Persichetti included the following note on the score:

Psalm for Band is a piece constructed from a single
germinating harmonic idea.
There are three distinct sectionsa sustained chordal mood, a forward
moving chorale, followed by a Paean culmination of the materials.
Extensive use is made of the separate choirs of instruments supported by
the thematic rhythms in the tenor and bass drums.
